Long story short guys, was doing some bulb changes on heater controls and changing stereo, and when I plugged everything back in it blew a shed load of fuses. I've checked them all and everything is back up and running apart from the following.

Heaters don't work now. They light up clock works but no response from the dials or switches,

Lost my trc and snow button function and abs lights is constantly on, think they will be linked.

And my fuel gauge has stopped. The light just flashes away and reads empty.

All these were working right before something went pop. I've been through all the fuses and all look fine can't see any obvious blown ones, should I be changing any in particular just in case? Any one any ideas? All help welcome as I'm kinda lost.

Yeah I've been through all 3 of the fuse boxes-dunno why they aren't all in one place- and couldn't see anything. Would the diagnostics show up if there is a relay or anything away? Not really been anywhere to find out if traction control is kicking in or not. Will try machine and get back on again when I figure out what it says.

It won't tell you if a relay has gone but from memory when altezzas have a fault the dash will stick the engine management light on and flash the TRC light. But in sure I've read that it can just start flashing random things on the dash depending on the type of fault.

Good luck finding the problem I'm sure when you find it it'll be something small
